I had sent your question about the SD2 to italy and here is the answer i got..
QUESTION #1
1) Page 42 of the manual states that CONTROL 1EH (CC30) should control the Rotor for the tonewheel organ.
…..You are in right!!!
2) Myself and at least three others who own SD2 units have not been able to get the Rotor to work at all.
…..In order to select ROTOR ( or Leslie ) you have to use firstly this EXCLUSIVE strings
TYPE EFFECTS CHANNEL ASSIGN
F0H 26H 7BH 0BH 00H Chan Type F7H ------------- F0 26 7B 0B 00 02 01 F7 then send CC30 at 0, 64 or 127
Chan: 00H - 1FH Type: 0 = no effects 3 = Chorus
1 = Leslie 4 = Delay
3) 2 = Distorsor
……on CHAN you have to select which track you would use than on TYPE select 1 (Leslie )
Don’t forget ….Leslie or Rotor work instead of Chorus ( or Distortion or Delay as showed on page 44 )
3) We can get the tonewheel organ drawbars to work just fine, also some of the other effects, using conversions of hexadecimal to the proper CC numbers, as one would expect.
At the bottom of Owner manual there’s an example of it :
DRAWBARS SELECTION
Controller 0 Value 67 Bank MSB Program Change 0
Drawbar Controller: 20 = 16’ Value: 0-127 24 = 2 2/3 Value: 0-127 28 = percussion 4’ Value: 0-127
21 = 8’ Value: 0-127 25 = 2’ Value: 0-127 29 = percussion 2’ 2/3 Value: 0-127
22 = 5 1/3’ Value: 0-127 26 = 1’ 3/5 Value: 0-127
23 = 4’ Value: 0-127 27 = 1’ Value: 0-127
I.E ( in order to send a drawbars data 16’- 8’- 4’)
Controller 0 value 67 Controller 20 value 127 (16’) Controller 23 value 127 (4’)
Program change 0 Controller 21 value 127 (8’)
..no needs an hexadecimal value ..but simple Controllers
Is there perhaps a misprint in the manual or is there something we are missing that we need to do?
We need the Rotor function.
In detail ..to obtain Rotor you have to switch before between Chorus ( or else ) and than will have Rotor….
